Solar Roast Coffee: On the go[2], that is. While the Pueblo coffee shop opened in 2005, Nathan Stern and Chris Bass rolled out the panels on the mobile branch just last October.

Foundations: The guys originally wanted to open a board game themed coffee joint, but a new shop holds a lot of risk, especially for first time small business owners. So, they approached the Pueblo establishment to help bring the brand to Denver.

Now serving: Stern says it’s a challenge to come to food truck events where people want, well, food, and not necessarily a drink. “We rely on the concept and brand, plus our visuals to entice people to get a drink with their meal,” he said. The truck serves your standard coffee shop drinks, along with two signature Solar Roast creations.

Food philosophy: The truck might be bright yellow, but this truck prefers green. At least when it comes to the coffee. That’s why the truck is outfitted with solar panels right on the roof, which help power inside operations. Under the serving counter is a bank of batteries which get their power from the panels up top. The batteries power an inverter, which runs the blender, fridge, cash register, etc. The only thing that isn’t solar powered? The espresso machine requires too much power. But, besides that, the batteries hold enough juice to run for 30 hours.

Popular dish: Signature coffee concoction the “Pueblo Mocha” contains two additional espresso shots and cyan pepper. A large is the most expensive menu item at $6.

A small cup of coffee costs $2, while most drinks average around $3.50.

Grab a sun-powered cuppa from 11 a.m. to 2 p.m. on Thursdays at Civic Center. Follow Solar Roast Coffee on the road at their Facebook page[2].
